As others have said, it is not dangerous to go to sleep. However, becoming unconscious, and not being able to be aroused, could be a sign of a more serious brain injury. In that case, imaging the brain with a CT scanner can rule out bleeding in the brain. The horror stories you have heard about would be people dying from bleeding, not concussions. There is no cure for a concussion. For people who have more serious concussions, neurologists or psychiatrist/psychologists can provide therapy long term to cope with and improve any cognitive deficits.
